FAQ
Where are the DIP switches located?
On RDG, the DIP switches are located at the rear of the unit.
On RDF semi flush-mount units, the DIP switches are located on the inner
side of the front panel.
Where do I find the correct DIP switch position?
They are shown in the Mounting Instructions and on the product.
How can I set the parameters?
The procedure for setting the parameters (“Service” or ”Expert” level) is described
in the basic documentation of the thermostats.
When do I have to set the control parameters?
In general, it is not necessary to readjust the parameters since the unit works correctly
with the factory-set parameters. Nevertheless, in some rare cases, you need to readjust
the application-specific parameters during commissioning to enable the desired functions.
For that, access the “Expert” level. For detailed information, refer to the technical docu-
mentation.
The control parameters on the “Service” level for HVAC systems and for adjusting
the user interface can be accessed at any time.
It is possible to reload the default timer setting?
Yes. The default timer setting (A1… A8) and the procedure for reloading are described
in the technical documentation.
It is possible to reset the control parameters?
Yes. The factory-set control parameters can be reloaded via parameter P71 by changing
the value to “ON” and by confirming with the buttons. For detailed information, refer
to the technical documentation.
How to check the current settings and the installation?
On the “Expert” level, some diagnostic parameters (d01, d02, ….) are available for
checking the selected application, the status of the inputs, and for testing the
3-position outputs. For detailed information, refer to the technical documentation.
